Would it run?
And if It does, am I allowed to use it at Worlds?

But now I found that the same program does not set the hold during the disabled period, they always start at coast mode works. Then I flipped through the forums, and it seems that hold mode can be achieved prior to VexOS 1.0.10, and after VexOS 1.0.11 the disable period is not settable, it seems to be forced to be set to coast mode. What I want to ask is that now that …

If you really need something to stay up when in coast mode I would suggest using rubber bands or make your pneumatics close in their idle position.
